Abstract

L'invention porte sur une chambre de combustion d'un moteur Diesel à pistons alternatifs et à injection directe où l'injection se fait dans un évidement (102) pratiqué dans le piston. Le piston (100) comporte une chambre de réaction (106) jouxtant l'évidement et communiquant avec la chambre de combustion par un orifice (108) discret. L'orifice est situé de manière à décharger les produits de réaction de la chambre de réaction au centre du nuage (112) de suie formé par la combustion du combustible à chaque cycle.
